Newton's First Law of Motion

An object at rest will stay at rest unless an unbalanced force acts on it.

• True

• False

An object's tendency to resist (not) change its state of motion is called ____________.

• gravity

• force

• inertia

• friction

While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?

• You will continue to slide until a force makes you stop or change direction.

• The force of gravity will make you keep your velocity.

• You will not go far.

How does the water in the balloon show inertia after it is popped?

• At first, the water tries to stay in the same shape/location before gravity takes over.

• The water splashes down on the unexpecting kitten.

• The water accelerates towards the kitten.

An object in motion (or at rest) will to stay in motion (or at rest) until an outside force acts upon it.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Newton's 4th Law

Whats Newtons First Law?

• The more force applied to an object the faster it will accelerate.

• An object in motion will stay in motion and an object at rest will stay at rest unless acted by an outside force.

• for every ection there is an equal and oposite reaction

According to inertia, without the seatbelt the driver would...

• Stop with the car.

• Continue moving forward.

• Move backward.

The skateboarder does NOT see the stick on the ground and is approaching FAST. Based on what you know about inertia, what do you think will happen next?

• The skateboarder will hit the stick and stop.

• The skateboarder will hit the stick and go flying forward but the skateboard will stop.

• The skateboarder will hit the stick and bounce backwards.
